As is usually the case, the Ultra Music crew will be in attendance this year for the 24th annual Winter Music Conference, and they’re throwing another bash to celebrate.

The two-day event dubbed Ultra Music Festival 11, will take place over March 27 and 28 in South Beach, Miami’s Bicentennial Park. It also seems that Ultra has stepped up the lineup this year, with Cut Copy, Crystal Castles, Roni Size, Busy P, and others slated to perform.

Tickets are currently on sale at the festival’s site. Limited two-day passes go for $99.95 right now, but will go up to $129.95, then $149.95, as the festival date approaches, so step to it.

And here’s the line-up so far: Santogold, Roni Size, Bloc Party, The Ting Tings, Tiësto, Cut Copy, Deadmau5, Crystal Castles, The Presets, Hercules and Love Affair, Simian Mobile Disco, Busy P, Carl Cox
